Product Description

The Lumicon Low Profile 1.25" Focuser for Newtonian on 3in Base is a high-precision, pin-and-groove type helical focuser. The draw-tube does not rotate. The low-profile design quickly and easily converts your standard Newtonian to a camera-ready telescope. For visual use, the smooth focusing brings out the very best in your telescope's optics. Accessories that take up back-focus, such Lumicon's popular 1.25" Multiple Filter Selector, can be used with ease and convenience. The U-groove base aligns and sits flush on any telescope tube with a radius of 3.5" or larger.
